Multi select combo box with Checkbox in Silverlight 4.0

I found multi select combo box on msdn and I converted into Silverlight 4.0, just copy "Main.Xmal"

“IN” clause in LINQ

"IN" Clause in LINQ

Some time we have a requirement to select records with more than one criteria as same as "IN" clause with SQL like:

"Where EmpId IN (1,2,3)"

We can do this with LINQ to Object also, we have to use "Contains" function like below

public static Employee[] GetEmployee(string[] EmpID)

{

        return (from p in GetEmp()

        where EmpID.Contains(p.EmployeeID)

        select p).ToArray<Employee>();

}
